Question 1

What must occur for a chemical reaction to take place according to Collision Theory?

  • Only collision is necessary
  • Collision with sufficient energy and correct orientation is necessary
  • Pressure needs to be increased

💡 Hint: Think of the three criteria stated in collision theory.

Question 2

True or False: Catalysts affect the final products of a reaction.

  • True
  • False

💡 Hint: Consider what happens to the catalyst throughout the reaction process.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a reaction A + B → C. If the rate expression is found to be Rate = k[A]^2[B], and it’s observed that doubling the concentration of A doubles the rate while doubling the concentration of B quadruples the rate, discuss what this implies about the orders of reaction with respect to A and B.

💡 Hint: Check how changes in concentration correlate with observed rate changes.

Question 2

Describe an experiment to determine if the reaction 2A + B → products is first order in A and second order in B. Design a series of trials and analyze your method.

💡 Hint: Think about the importance of controlling variables.
